Then the Lord said to Moses, Go in to Pharaoh and say to him, This is what the Lord, the God of the Hebrews, says: Let my people go so that they may give me worship. For if you will not let them go, but still keep them in your power, Then the hand of the Lord will put on your cattle in the field, on the horses and the asses and the camels, on the herds and the flocks, a very evil disease. And the Lord will make a division between the cattle of Israel and the cattle of Egypt; there will be no loss of any of the cattle of Israel. And the time was fixed by the Lord, and he said, Tomorrow the Lord will do this thing in the land. And on the day after, the Lord did as he had said, causing the death of all the cattle of Egypt, but there was no loss of any of the cattle of Israel. And Pharaoh sent and got word that there was no loss of any of the cattle of Israel. But the heart of Pharaoh was hard and he did not let the people go.
